The jumper of the optical module, namely the fiber optic jumper used to connect the optical module, is an indispensable component in the optical communication system, used to achieve reliable optical signal transmission between the optical module and other equipment (such as fiber. We know that optical transceivers are usually used with optical fiber jumpers. However, due to different applications, the operating wavelengths, interface types, and transmission distances of different optical transceiver module are different. Therefore, the optical fiber jumpers must be. This technology's core is fiber jumpers, which are also details for patch cords, including LC duplex and SC fiber optic types used to connect network devices. This article focuses on fiber jumper cables, presenting all the needed materials covering their types, applications, and technical. Optical fiber jumpers can be divided into common silicon-based optical fiber single-mode and multi-mode jumpers according to different transmission media, and other optical fiber jumpers such as plastics as transmission media; According to the structure of the connector, it can be divided into: FC. MPO (Multi-fiber Push On): MPO is a standard multi-fiber push-pull optical connector interface designed for high-density fiber connections. It provides stable connectivity and fast plug-and-play operation. As an industry-standard interface specification, MPO defines the mechanical structure. Fiber jumpers (also known as fiber optic connectors), which is the access fiber optical connector module, also have a good variety, and are not interoperable with each other.
